Aldo Leopold’s description of passenger pigeon abundance in the 19th century
aptly describes their great numbers and ecological impact in the Historic era, but

North America? Zooarchaeologist Steven Kuehn summarizes passenger pigeon
finds from the archaeological record of Illinois and Wisconsin, including recent
discoveries from the Cahokia region, and discusses how the data provide insight on
the prehistory of the passenger pigeon.
